B.J. Linnenbrink enters the 2016 track & field season with a new title, earning a promotion to associate head coach after joining the Blue Devil coaching staff assistant coach in July of 2009. Linnenbrink works primarily with Duke's men's and women's throwers while also overseeing the officials and volunteers that help run the Duke track & field meets at Morris Williams Stadium.

Linnenbrink helped guide Duke’s throws program in 2016. Michael Foley set a new outdoor school record in the hammer throw with a mark of 195-5 (59.56) and Thomas Lang received second team All-ACC accolades in the javelin, and was named ACC Outdoor Performer of the Week (Apr. 19). Four women and seven men qualified for the ACC Championships, and Lang (javelin), Stephen Boals (shot put) and Christine Streisel (javelin) qualified for the NCAA Outdoor East Preliminary Round.

The 2015 season was a successful campaign for Linnenbrink, helping both Thomas Lang (men’s javelin) and Erica Brand (women’s discus) reach the NCAA Outdoor Championships, highlighted by Lang garnering first team All-America honors with a sixth-place performance. Under Linnenbrink’s tutelage, the Blue Devil corps set or reset four of the 12 throwing records and combined for 19 event wins during the 2015 indoor and outdoor seasons, including a second consecutive outdoor ACC title for Lang in the javelin.

The Blue Devil throwing program continues to perform at a high level with Linnenbrink at the helm. In 2012, the throwing program had one of its best performances in school history, including sophomore Michelle Anumba accomplishing the task of being the first Duke female thrower to earn first team All-America honors. Under Linnenbrink’s direction, four throwers qualified for the 2012 NCAA Outdoor Track and Field Championship: Anumba (shot put), Michael Barbas (shot put), Erica Brand (discus) and Andrea Hopkins (javelin). Also in the outdoor season, Anumba (shot put) and Shannon Sullivan (javelin) finished first at the ACC Championships in their respective events while Barbas (shot put), Brand (discus) and Hopkins (javelin) earned All-ACC honors for finishing in the top three in their respective events.

Throughout his Duke tenure, Linnenbrink has guided four Duke throwers to a combined six All-America selections, helped five Blue Devils capture a total of seven conference crowns and has seen 15 student-athletes claim 27 All-ACC accolades.

Prior to his arrival at Duke, Linnenbrink held a similar position at Notre Dame from 2003-07. During that period, he tutored 15 NCAA Regional qualifiers and 17 All-BIG EAST performers, including 2005 BIG EAST hammer throw champion Chip Roberts. In addition, he guided Notre Dame’s first female thrower to qualify for the NCAA Championships as well as the first Irish thrower to advance to the outdoor NCAA competition since 1945.

Linnenbrink saw his Irish throwers advance to the NCAA Mideast Regional 15 times in five seasons with two qualifying for the USATF Championships. Additionally, the Notre Dame top-10 lists were radically altered in almost every throwing event under his direction with his student-athletes claiming 10 top-10 efforts on the men’s side and a staggering 26 top-10 performances on the women’s side.

As a member of Notre Dame’s staff, he was part of five BIG EAST Coaching Staff’s of the Year - 2003 & 2005 men’s indoor, 2003 & 2006 men’s outdoor and 2006 women’s indoor.

A former NCAA and USATF Championship qualifier at Florida State, Linnenbrink owns the Seminole school record in the weight throw (20.91m/68-7.25) and ranks among the top-five in FSU history in the hammer throw (59.48m/195-2), earning All-Atlantic Coast Conference accolades as a senior.

Before his successful two-year stint at Florida State, Linnenbrink dominated at the junior college level, where he earned two NJCAA All-America honors at Johnson County Community College in Overland Park, Kan., in addition to seven All-Jayhawk East Conference awards.

Linnenbrink received a bachelor of science degree in physical education from Florida State in 2002 and in 2006, he earned his master of science degree in physical education from Emporia State.

He is a USATF Level II certified coach in throwing events.

Linnenbrink and his wife, the former Monica Hardy, married July 31, 2004. They have one son, James.
